Another incredibly NOOB question. So, if I get a NAS, and I buy a couple WD RED hard drives....
A - just because I have a 2 or 4 bay NAS, do all bays have to have a hard drive in them? Can I start with just 1 hard drive until I get more money to buy more?
B - Does the hard drive simply slide into place? Or, is there some bolting to do?
A. 1 is ok. You can add any number in future (but if you go with a RAID it takes a while to mirror from one to many)
B. My two Synology NAS's I've owned have clip in caddys. No small bolts required.
